ZHCSGH3A March 2016 – July 2017 TAS5782M
PRODUCTION DATA.
The TAS5782M device has a zero-detect function. The zero-detect function can be applied to both channels of data as an AND function or an OR function, via controls provided in the control port in P0-R65-D[2:1].Continuous Zero data cycles are counted by LRCK/FS, and the threshold of decision for analog mute can be set by P0-R59, D[6:4] for the data which is clocked in on the left frame of an I2S signal or Slot 1 of a TDM signal and P0-R59, D[2:0] for the data which is clocked in on the right frame of an I2S signal or Slot 2 of a TDM signal as shown in Table 10. Default values are 0 for both channels.
ATMUTECTL | VALUE | FUNCTION |
---|---|---|
Bit : 2 | 0 | Zero data triggers for the two channels for zero detection are ORed together. |
1 (Default) | Zero data triggers for the two channels for zero detection are ANDed together. | |
Bit : 1 | 0 | Zero detection and analog mute are disabled for the data clocked in on the right frame of an I2S signal or Slot 2 of a TDM signal. |
1 (Default) | Zero detection analog mute are enabled for the data clocked in on the right frame of an I2S signal or Slot 2 of a TDM signal. | |
Bit : 0 | 0 | Zero detection analog mute are disabled for the data clocked in on the left frame of an I2S signal or Slot 1 of a TDM signal. |
1 (Default) | Zero detection analog mute are enabled for the data clocked in on the left frame of an I2S signal or Slot 1 of a TDM signal. |
